This CD player was manufactured in October of 1996. I found it after packing up a household. I don't know if the AZ number is the model number or not. I could not find a MODEL NO. It is a MAGNAVOX Bitcheck Concersion DBB (Dynamic Bass Boost). It has a 12 play mode. I've put 2 new AA batteries in it. It uses earphones. A CD goes around but no sound comes thru. I checked the MAGNAVOX website for an online manual but do not find this model. They probably don't manufacture it after all this years. Can someone help me out?
